Vaporstat L408J1017 stopped working
After six weeks my Vaporatat L408J1017 seems to have malfunctioned.
The Vaportat was set to a cut out of about 10 ozs on a two a two pipe steam system. The Vaportat is on a new pigtail along with the pressure gauges, no snubber. Everything worked as expected for about six week.
Today I noticed a long burn on the boiler, and upon checking saw that the pressure was heading north of 1 psi on the low pressure gauge (1-5 psi). The pressure gauge is mounted on the same pigtail as the Vaportstat. After some observation, it was clear that the Vaporstat was not cutting out on pressure as expected.
As a back up, the Pressuretrol is managing the cut out at about 1.5 psi (more or less).
The Vaportstat is relatively new (six weeks old). Anyone have any suggestions on how to troubleshoot? Can anyone recommend a replacement model that might be more reliable?
